Earthing cautions at handling Pick-up
- Because the laser diode in optical Pick-up is subject to get
out of order due to the potential difference occurring by
electricity load charged in clothes or bodies, observe the
following earthing items at handling.
1) Body earthing(hand) : Be sure to wear a wrist strip with
one side earthed.(Impedance : Below 104).
It removes the electricity formed in body.
2) Work table earthing : Put the earthed conductive
plate(Impedance : Below 104) such as copper plate on
work table.
3) Cautions for clothes : Do not have any clothes touch with
Pick-up because the electricity formed in clothes is
destroyed easily.
n Cautions at Service
1. General Items
1) Be careful not to have your eyes or a part of body touch
with laser diode at repair because this product uses laser
diode.
2) Do not disassemble Pick-up at repair. If the laser diode is
bad, replace the entire Pick-up.
3) Keep away from TV or other electrical units at repair to
prevent influence from surrounding units.
4) If you replace the parts during repair, be sure to unplug
the power cable before replacement.
5) If you insert a disc into the drive, be sure to load it
correctly.
6) Because this unit can't be used by itself, surely mount it
on PC (486 DMA support) and check the operations in
use of private device driver floppy diskette. Refer to
Instruction manual.
7) This unit has many parts with features related to safety
and especially, for essential parts, the importance is
indicated on circuit diagram and part list.
Be certain to use the parts with same specifications at
replacing these parts.
